Making Watermelon Mochi is simple if you follow these clear steps:

1. Prepare Watermelon: Cut your watermelon into bite-sized cubes. Pat them dry with a paper towel to remove excess moisture.
2. Mix Dry Ingredients: In a large mixing bowl, combine sweet rice flour and sugar.
3. Add Water: Gradually add water, stirring until smooth without lumps.
4. Prepare Steamer: Fill a pot with water and bring it to a simmer. Place a heatproof dish or a bamboo steamer inside, making sure it doesn’t touch the water.
5. Steam Mixture: Pour the mochi mixture into the dish. Cover with a cloth or lid and steam for about 15 minutes or until it becomes translucent.
6. Cool the Mochi: After steaming, carefully remove the dish from the pot. Let it cool for about 10-15 minutes.
7. Dust with Cornstarch: Once cool enough to handle, dust a clean surface with cornstarch. Turn the mochi out onto the surface and sprinkle more cornstarch on top to prevent sticking.
8. Shape Mochi: Divide the mochi into portions and flatten them into round disks using your hands or a rolling pin.
9. Wrap Watermelon: Take a piece of flat mochi and wrap it around a watermelon cube, pinching it closed to seal in the fruit.
10. Repeat: Continue this process until all your watermelon cubes are wrapped in mochi.
11. Chill: Place the finished Watermelon Mochi in the refrigerator to chill before serving.

Following these steps will guide you in creating this delightful and unforgettable treat.
